What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The relationship between chest radiograph (CXR) findings of pulmonary congestion and invasive hemodynamics and clinical outcomes in patients with cardiac diseases is unclear. We assessed the correlation between a CXR-based congestion score (RxCS) and the mean pulmonary artery wedge pressure (mPAWP) and the prognostic impact of RxCS and mPAWP in severe aortic stenosis (AS). Methods: In 471 patients with severe AS undergoing right heart catheterization and upright CXR, the RxCS was calculated (6 items, maximum score: 10 points) independently by 2 radiologists (average value taken) blinded to clinical data. Congestion was defined as an RxCS > 1. Four patterns were defined based on the presence or absence of congestion (C+ or C-) and elevated (> 15 mm Hg) or normal mPAWP (P+ or P-). Results: The median (interquartile range) RxCS was 1 (0-2). Patients with an RxCS > 1 (n = 207) had a higher mean right atrial pressure, mean pulmonary artery pressure, mPAWP, and pulmonary vascular resistance than patients with an RxCS ≤ 1 (n = 264). However, the correlation between the RxCS and the mPAWP was moderate only ( Conclusions: In AS patients, RxCS and mPAWP have a significant but moderate correlation. Both RxCS and mPAWP provide prognostic information.
